Where are you defining $message? And in your second example, you are using $requester_message1 but your wordwrap is being returned to $requestor_message.

Here is the entire file. I'm echoing the concatenated message and it looks right, but for some reason the mail function doesn't send when I use it. If I substitute either of the original ($requester_message1 or $message) it works.
